Arquitectura general del sistema LTE
Abstract
En el siguiente artículo se describe, en apretada síntesis, la arquitectura de una red de comunicaciones móviles basada en las especificaciones del sistema LTE (Long Evolution Term). Para ello, a partir de un análisis inicial de la arquitectura genérica adoptada en los sistemas celulares 2G/3G actuales, se identifican los elementos fundamentales que componen la arquitectura de red de toda la familia de sistemas especificada por 3GPP (3rd Generation Partnership Project). Esta identificación permite enmarcar de manera clara y precisa cuáles son, y a qué criterios básicos de diseño obedecen, los nuevos componentes introducidos por el sistema LTE respecto a las redes GSM (Global System for Mobile Communications) y UMTS (Universal Mobile Telecommunications System).
